APPARATUS FOR SEPARATING FAT FROM WATER.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed February 12, 1908. Serial No. 416,568.

To all whom it may concern: I Be it known that I, MAUnIoE Lone, a citil zen of the Empire of Germany, residing at i New York, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Apparatus for Separating Fat from Water, of which the following is a specification.

This invention relates to certain improvements in apparatus used for separating and collecting fats and solid particlesfrom drain or dish-water and other liquids, which apparatus is specially adapted for the-drainpipes of the kitchen-sinks of hotels, restaurants, meat-markets, private dwellings and the like.

Apparatus for separating fats and other solid particles from'water, comprising an exterior vessel provided with an overflowchannel, an interior vessel closed at the top and open at the bottom-located within the outer vessel, a chamber within said vessel, a channel for admitting the liquid to the inner within said inner vessel for directing the liquid toward the chamber in the inner vessel, are well known, but they failed in collecting. all the fat and heavy sediments, especially when. there was an intermittent and sudden flow of water from the drain-pipe, so that a considerable quantity of the fat and other matters is carried on to the outflowchannel without being separated from the water. Furthermore, the convenient de'-- taching and separation of the interior parts for removing the fat collected in the lunar chamber and the sediment collected'at the hottomof the outer chamber, and the convenient cleaning of the parts, could not be successfully accomplished The object of this invention is to furnish an apparatus for separating fat and other matters'from water in which the disadvantages stated may be overcome, the fatand other matters completely separated from the water and then removed by the detachabilityof the arts from each other; and for this purpose tile invention consists of'an ap paratus for separating fat from water, which comprises an outer vessel having a removable erforated cover and'an overflow-trough adacent to the upper edge of thevessel, an inner vessel open at the lower end and provided with an impcrforate detachable-cover, said imperforate cover having a flange' surrounding the same and outlets at opposite sides thereof, channels communicatin with said. outlets, and upwardly-inclined l ges' at the lower ends of said channels for conducting the drain-water into the interior chamber below the imperforate cover.

The invention consists further of certain details of construction which will be fully described hereinafter and finally defined in the claims.

In the accompanying drawings, Figure 1 represents a plan-view of my improved apparatus for separating fat from water, shown. with the cover removed. Figs. 2 and 3 are ,vertical transverse sections through the apparatus taken respectively at right angles to each other on lines 2, 2, and 3, 3, Fig. 1, Fig. 4 is a perspective view. of the detached cover for the interior vessel, shown as detached from the same, and Fig. 5 is a plan-view of the interior vessel with the cover removed from the same.

Similar letters of reference indicate corresponding parts throughout the several figures.

Referring to the drawings, a represents the outer vessel, which is closed at the bottom and open at the top, and which is surrounded by an exterior overflow-trough b the outer wall of which extends above the upper edge of the vessel a-. A cover 0 is supported on the outwardly-bent flange of the overflowtrough b by means of angular lugs attached nearits outer edge and prevented thereby against lateral displacement. The cover 0 is provided with a number of perforations in its central depressed or dishing portion. The perforations 1n the cover serve for distributmg the drain or other water to the interior of the outer vessel so as to prevent sudden inflows and rushes of the same. The outer vessel a is preferably made of rectangu ar shape, but it may be made of round, oblong or other shape. The overflow-channel b recelves the Water after the fat and sediments have been separated therefrom. From the overflowtrough 1; leads a suitable drain-pipe Z) to the sewer or any other suitable depository.

-In the outer vessel a is supported an interior'vessel (1 whose cross-section corresponds 'With the cross-scction of the outer vessel, but which is somewhat smaller so as to leave a free passaqewaybetwe'en the inner and outer vessels. The inner vessel is formed of vertical Walls and is open at its lower end, its

"channel is provided, adjacent to its u per. 10.

end, with outwardly-bent lugs d by w ch 1 the inner vessel 3 is supported on the upper edge of the' outer vessel a, both channels communicating at their upper ends with the space above the cover of the inner vessel, and at their lower ends with upwardly-inclined ""7 ledges d which form pockets with the channels, and which ledges are e nal in width with the width'of the vertical c annels e, and

connected by sid'e-walls'with the side-walls.

channels 0 to the interior ofthe inner vessel in upward direction, so as to deposit the fat -carr1ed'along with the li uid'on the sidewalls of the inner vessel an under-surface of p the cover (3 I of a plate which is raised sli htlytowards the, center, and which is provi ed with vertical The cover (1 of the inner vessel is formed walls d at the under-side that fit snugly within the walls of the inner vessel at its up er end. Above the toplate ofthe cover 1 extend upright flanges which flan es are .cut away at opposite sides in line, with the channels c formed between the inner' and. outer vessels, so as to form outlets communieating with theupper ends of the channels.

The matter contained in the drainwater are '00 ected in the'bottom of the outer vessel. When the outer vessel is entirelyfilled with water, the continued supply.

The ledges d serve for conducting the liquid which-flows ClOWIL'tlIIOIlgh the cline will cause an overflow at the upper edges into the overflow-channel and from the same by the drain-pi e to the sewer. A perfect separation of t 1e fatty matter and sediments from the water takes place, the fat being congealed on the cool surfaces of the inner chamber and its cover, while the water standing above the same in the outer vessel,'after de ositing .the heavier sediments, will flow 0 over the edge of the outer vessel in a com- 7 5 paratively clear state. After a certain accumulation of fat has taken place in the inner vessel, the'outer cover. is removed. and the inner vessel bodily removed withits deposit I of fat from the outer vessel, after which the 0 cover of the inner vessel is lifted off and the fat removed from the inner surface of the cover and the walls of the inner vessel, while at the same time the inner vessel with'its channels and the outer vessel and cover are 35 thoroughly cleansed. The sediments collected at the bottom of the outer vessel are removed and utilized, while'the fatty matter regained is purified and used in the arts.

.The advantages of my improved fat-sepa- .ratin apparatus are that. the same consists of o y our arts, viz, the outer vessel and its cover, and the inner vessel and its cover, which are made detachable from each other for the convenient rempving of the fat and cleaning of the ap, aratus, whereby the same is better adapte for the kitchen-sinks of hotels, restaurants, boarding houses and private residences.
